contra-rotating axial-flow fan

基本解釋

By means of numerical simulation, the research on inner-flow of mining contra-rotating axial flow fan working under low flow rate condition was made.
通過數(shù)值模擬手段，對一礦用對旋式軸流式通風(fēng)機(jī)小流量工況內(nèi)部流動進(jìn)行了深入研究。
The working principle and key parameters of the blade separator were introduced, and tests on the performances of adding the separator on the contra-rotating axial flow fan were carried out.
介紹了葉片分離器的工作原理和關(guān)鍵參數(shù)，并對加裝了葉片分離器的對旋軸流風(fēng)機(jī)進(jìn)行了性能測試試驗。
Made some researches about internal flow of contra-rotating axial flow fan under low flow rate, blade separator was designed to control internal flow and was proved effective by experimentation.
通過對對旋式軸流通風(fēng)機(jī)小流量特性的分析，并利用實驗驗證分離器能夠控制和改善對旋風(fēng)機(jī)小流量內(nèi)部流動特性，從而獲得葉片分離器設(shè)計和使用的一些關(guān)鍵技術(shù)。
